Does anyone really care where the speech is delivered? Most of the people watch the State of the Union address remotely anyway, so it may not matter if the speaker is being foolish about holding the House Chamber as a hostage.
This is not her chamber! This is the people’s chamber! It does not belong to the Democrat Party — It belongs to all Americans! Just because she has a majority of her members who are willing to vote for whatever procedural vote she wants, doesn’t mean it is a proper use of her power. Nobody has the right to use “the people’s house” to be vindictive.
At the end of the day, I believe the Speaker did more harm to herself, her reputation and the reputation of the Democrat Party than what can be measured.
